NEW YORK (

TheStreet

) -- Stocks shed more than 1% Thursday after running up earlier in the week ahead of

Federal Reserve

Chairman Ben Bernanke's big speech on Friday.

The pullback was exacerbated by a swift anxiety-inducing selloff in Germany and the surprise news of Steve Jobs' resignation as CEO of

Apple

(AAPL) - Get Report

late Wednesday.

The major U.S. equity indices finished near session lows with the

Dow Jones Industrial Average

down by 171 points, or 1.5%, at 11,149. The

S&P 500

lost 18 points, or 1.6%, at 1159, and the

Nasdaq

fell 48 points, or 2%, at 2420.

"The big problem right now is that the technical conditions are supportive of some selling," said RealMoney Contributor Rev Shark in a

recent blog post. "We had a decent bounce over the last two days, due in large part to hope that Bernanke will give the bulls some ammunition, but now a lot of folks are wondering if there really is anything the Fed can do, other than give us some happy talk."

German markets came under pressure late in the European trading session. The DAX in Frankfurt closed off of its lows of the session, but still finished 1.7% lower. The quick drop came on speculation that the country's public finances are weakening and market restrictions may be coming from regulators, according to a

Bloomberg

report.

The FTSE in London dropped 1.4%. Earlier, both Hong Kong's Hang Seng and Japan's Nikkei jumped 1.5%.

"Some investors are trying to lock in some profit," said Robert Pavlik, chief market strategist at Banyan Partners, Thursday morning. "Investors are perplexed as to what to do next -- Get in? Bottom fish? Wait on the sidelines? There are a lot of questions out there."

Investors appear to be showing some caution ahead of Bernanke's speech at the Kansas City Fed conference in Jackson Hole, Wyo., on Friday. It was during the same conference a year ago that Bernanke first proposed a second round of quantitative easing to bolster the economy.

During the first three sessions of the week, stocks had surged

as lack of major negative headlines gave way to speculation over Friday's speech. The Dow had climbed more than 500 points, or 4.56%, in the prior three trading days alone.

stepping down from his position as CEO to be replaced by Chief Operating Officer Tim Cook. Jobs will continue to serve as chairman of Apple's board.

"Recent economic data has collectively provided little reassurance about the strength and trajectory of the U.S. economy," said Jim Baird, chief investment strategist at Plante Moran Financial Advisors. "Despite the fiscal and monetary stimulus that has been injected over the past few years, consumers continue to have their figurative eye on the door. They lack confidence in the direction of the economy and are struggling under the weight of excess debt without meaningful growth in asset values and limited income growth."
